States of Matter

• A class of elements characterized by physical properties that include shininess, malleability, ductility, and conductivity.


  Metal

  
• An element that tends to be a poor conductor of heat and electric current; these generally have properties opposite to those of metals.

  Non-metals

  
• A pure substance that is made up of two or more different types of atom chemically bound together

  Compound

  
• A substance made up of only one type of atom

  Element

  
• A cluster of atoms that makes up an element or a compound

  Molecule

  
• Chemical properties


  Characteristics of a substance that determine how it will react with other substances.

  
• Compound


  A pure substance that is made up of two or more different types of atom chemically bound together

  
• Element


  A substance made up of only one type of atom

  
• Molecule


  A cluster of atoms that makes up an element or a compound

  
• properties of solids


  ★ Extremely hard to compress (squeeze)

  ✔︎ They are packed in a regular pattern with almost no space between them

  ★ Solids have a fixed shape and cannot flow place-to-place

  ✔︎ The particles can vibrate but cannot move
• properties of liquids


  ★ Extremely hard to compress (squeeze)

  ✔︎ They are packed in a regular pattern with almost no space between them

  ★ Liquids take the shape of their container

  ✔︎ The particles in a liquid can move
• properties of gases


  ★ Extremely easy to compress (squeeze)

  ✔︎ There are large gaps between particles

  ★ Gases fill up and take the shape of their container

  ✔︎ The particles move quickly and randomly
• How do you change state?

  ★ Put energy in/out

  ★ The stronger the forces between particles

  ➜ The more energy needed to change state

  𐬽 The higher the m.p & b.p.
